The BI-EKF algorithm estimates stator stationary axis components of the stator fluxes, ?sa and ?sß, the rotor angular velocity, ?m, the rotor resistance, R'r, the stator resistance, Rs, the load torque involving the viscous friction term, tL, and the reciprocal total inertia of the IM and load, ?? = 1/jT, as well as stator stationary axis components of stator currents, is? and isß, which are also measured as output. The simulation results prove very satisfying performances of the BI-EKF algorithm and therefore the speed-sensorless DTC system. © 2011 IEEE.eninfo:eu-repo/semantics/closedAccessInduction motorsSensorless controlStatorsTorque controlLoad torquesRotor resistancesSpeed-sensor lessStator currentsStator fluxStator resistanceViscous frictionExtended Kalman filtersConference Object34334610.1109/ACEMP.2011.64906212-s2.0-84876501942N/A
